Superior Adhesion of Monolayer Amorphous Carbon to Copper

Advanced Materials, EarlyView.
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...

A Multifunctional Binder for Current‐Collector‐Free Zn Powder Anodes

Advanced Materials, EarlyView.
By introducing abundant polar groups as Zn2+ absorption sites and hydrogen bond arrays, a protein structure‐derived binder for ZP anode and iodine cathode is proposed. This design can regulate the Zn2+ flux, benefit the formation of free‐standing electrode, inhibit the side reactions, suppress the shuttle effect of polyiodides, and enable the large ...

Characterization and Inverse Design of Stochastic Mechanical Metamaterials Using Neural Operators

Advanced Materials, EarlyView.
This study presents a DeepONet‐based machine learning framework for designing stochastic mechanical metamaterials with tailored nonlinear mechanical properties. By leveraging sparse but high‐quality experimental data from in situ micro‐mechanical tests, high predictive accuracy and enable efficient inverse design are achieved.

Full Wafer Scale Manufacturing of Directly Printed TiO2 Metalenses at Visible Wavelengths with Outstanding Focusing Efficiencies

Advanced Materials, EarlyView.
The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.

Controlling Lithium Surface Diffusivity via 2D PtTe2, PdTe2, and NiTe2 Coatings for Anode‐Free and Lithium Metal Batteries

Advanced Materials, EarlyView.
Lithium plating mechanisms on 2D‐coated current collectors: PtTe2 coating enables rapid Li surface diffusivity, while PdTe2 and NiTe2 coatings shorten diffusion paths for Li adatoms. In addition, Li2Te, formed from PdTe2 and NiTe2 decomposition, reduces the critical nucleus size by lowering the interfacial energy between the electrolyte and deposited ...
